Struct TasksCapabilities 

pub struct TasksCapabilities {
    pub list: Option<TasksListCapabilities>,
    pub cancel: Option<TasksCancelCapabilities>,
    pub requests: Option<TasksRequestCapabilities>,
    pub extra: HashMap<String, Value>,
}

Core MCP protocol types and error handling Capabilities for tasks (per MCP 2025-11-25)

Structured capability advertisement for task operations. Presence of a sub-field (e.g., list: Some(...)) signals that the capability is supported.

Fields

list: Option<TasksListCapabilities>

Supports tasks/list operation

cancel: Option<TasksCancelCapabilities>

Supports tasks/cancel operation

requests: Option<TasksRequestCapabilities>

Supports task-augmented requests

extra: HashMap<String, Value>

Forward-compatible extension fields
